Solar Keratoses (or actinic keratoses) refers to a scaly or rough spot on the skin in areas with visible sun-damage. It is considered precancerous and the main concern is that it can develop into squamous cell carcinoma (SCC).
Actinic keratosis is a sign of abnormal skin cells that develop due to sunburn (UVB),
- Flat or thickened spots with scale
- Skin coloured, red or pigmented
- In sun-exposed areas
Risk of cancer
If a patient has more than 10 actinic keratoses, the risk of developing skin cancer is about 10%. A tender, thickened, ulcerated or enlarging actinic keratosis is suspicious of skin cancer and a biopsy should be performed.
